zeroarray
Abstract
Zero all elements in an array
Description
zeroarray sets all elements in an array to 0.
In the case of an audio array it is possible to pass a mask array of the same size as the audio array indicating which audio items in the array need to be zeroed (only those audio items will be zeroed for which the corresponding scalar item in the mask array is higher than 0). The mask can also be a table
Syntax
zeroarray iArr[]
zeroarray kArr[]
zeroarray aArr[] [, kMask[]]
zeroarray aArr[], imasktable=0
Arguments
- iArr / kArr / aArr: The array to zero
Output
Execution Time
- Init
- Performance
